Endpoint computing device network slice secure certificate provisioning and management system

ABSTRACT

An endpoint computing device network slice certificate provisioning and management system includes a core network system that is coupled to a Radio Access Network (RAN) system and configured to allocate a plurality of a network slices and make each of the network slices available for use in wireless communications via the RAN system. An endpoint computing device is configured to establish a first network connection with a first network slice included in the plurality of network slices and perform, via certificate provisioning wireless communications over the first network connection with the first network slice, certificate provisioning operations to provision a certificate for the endpoint computing device. The endpoint computing device may then use the certificate to verify at least one server device to provide at least one verified server device, and perform secure network communications with the at least one verified server device.

BACKGROUND

The present disclosure relates generally to information handling systems, and more particularly utilizing one or more network slices to securely provision a certificate on an endpoint information handling system and manage that endpoint computing device.

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Information handling systems such as, for example, server computing devices, networking computing devices, storage systems, desktop computing devices, laptop/notebook computing devices, tablet computing devices, mobile phones, and/or other computing devices known in the art, sometimes utilize digital certificates in order to provide for secure communications between those computing devices (e.g., between client computing devices and application server devices, as well as any other computing devices that would be apparent to one of skill in the art in possession of the present disclosure.) In some examples, such certificates may be utilized to provide secure communications via an Out-Of-Band (OOB) connection between a client computing device and a server device that is independent of an In-Band (IB) connection utilized by the operating system provided on the client computing device, and that may be used to perform management operations such as security operations, service operations, and/or other operating-system-agnostic, client computing device management operations known in the art. However, the cost and complexity associated with securing the OOB connection has been a barrier to the adoption of the OOB management discussed above. For example, conventional certificate provisioning that is performed to secure an OOB connection between a client computing device and a server device is often performed using a USB device (e.g., installing a certificate stored on the USB device on the client computing device so that the server device may verify that computing device, which is typically not an viable option when many client computing devices are being deployed due to the time requirements associated with it), or by providing a second secure network adapter device in the client computing device (in addition to a first network adapter device that is used to perform IB networking operations) that is dedicated for OOB networking operations, each of which are associated with additional costs and complexity in provisioning a certificate on that client computing device. Furthermore, a variety of additional software is required on the client computing device in order to validate the client computing device with the server device using the certificate, perform port filtering operations, and/or provide other software operations known in the art, while complex infrastructures are required on the server side to enable the OOB operations discussed above.

Accordingly, it would be desirable to provide a computing device certificate provisioning and management system that addresses the issues discussed above.

It should be understood that other buses and intermediate circuits can be deployed between the components described above and processor 102 to facilitate interconnection between the components and the processor 102.

Referring now to FIG. 2, an embodiment of an endpoint computing device multi-network slice utilization system 200 is illustrated. In the illustrated embodiment, the endpoint computing device multi-network slice utilization system 200 incudes a core network system 202. In an embodiment, the core network system 202 may be provided by the IHS 100 discussed above with reference to FIG. 1, and/or may include some or all of the components of the IHS 100, and in specific examples may include server devices, switch devices, storage devices, and/or other core network system components connected together to provide a 5G core network system that may be operated by a wireless provider (e.g., AT&T® Mobility of Atlanta, Ga., United States; SPRINT® Corporation of Overland Park, Kans., United States; VERIZON® Wireless of New York, N.Y., United States; etc.) and may include any combination of physical and/or virtual components that are configured to provide 5G wireless communications. However, while illustrated and discussed as physical and/or virtual components that provide 5G wireless communications, one of skill in the art in possession of the present disclosure will recognize that other components and/or component configurations may be utilized in a core network system to provide other wireless communications capabilities (e.g., 4G wireless communications) while remaining within the scope of the present disclosure as well.

In a specific example, the RAN system 204 may be a 5G RAN system including cellular towers that are configured to provide for wireless communications by endpoint computing devices utilizing network slices/spectrum allocated by the 5G core network system discussed above. For example, the RAN system 204 may provide an orchestration layer for wireless communications between communication devices and cellular towers, allowing wireless communications to then be exchanged by a RAN controller in the RAN system 204 via a Software Defined Networking (SDN) switch device and a separate control-based interface, the separation of which allows the RAN system 204 to be flexible and accommodate Network Function Virtualization (NFV) techniques utilized in 5G communications.

In a specific example, the endpoint computing devices 206 a-206 d may be provided by mobile phones, tablet computing devices, laptop/notebook computing devices, IoT computing devices, and/or any other endpoint computing devices that would be apparent to one of skill in the art in possession of the present disclosure. However, while a specific endpoint computing device multi-network slice utilization system 200 has been illustrated and described, one of skill in the art in possession of the present disclosure will recognize that the endpoint computing device multi-network slice utilization system of the present disclosure may include a variety of components and component configurations while remaining within the scope of the present disclosure as well.

Referring now to FIG. 3, an embodiment of an endpoint computing device 300 is illustrated that may provide any or all of the endpoint computing devices 206 a-206 d discussed above with reference to FIG. 2. As such, the endpoint computing device 300 may be provided by the IHS 100 discussed above with reference to FIG. 1 and/or may include some or all of the components of the IHS 100, and in specific examples may be provided by mobile phones, tablet computing devices, laptop/notebook computing devices, IoT computing devices, and/or any other endpoint computing devices that would be apparent to one of skill in the art in possession of the present disclosure. Furthermore, while illustrated and discussed as an endpoint computing device 300, one of skill in the art in possession of the present disclosure will recognize that the functionality of the endpoint computing device 300 discussed below may be provided by other devices that are configured to operate similarly as the endpoint computing device 300 discussed below.

In the illustrated embodiment, the endpoint computing device 300 includes a chassis 302 that houses the components of the endpoint computing device 300, only some of which are illustrated below. For example, the chassis 302 may house a processing system (not illustrated, but which may include the processor 102 discussed above with reference to FIG. 1) and a memory system (not illustrated, but which may include the memory 114 discussed above with reference to FIG. 1) that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a network slice engine 304 that is configured to perform the functionality of the network slice engines and/or computing devices discussed below. Furthermore, the memory system may also include instructions that, when executed by the processing system, cause the processing system to provide an application engine 305 that is configured to provide any or all of the applications discussed below as operating on the endpoint computing device 300.

The chassis 302 may also house a storage system (not illustrated, but which may include the storage 108 discussed above with reference to FIG. 1) that is coupled to the network slice engine 304 (e.g., via a coupling between the storage system and the processing system) and that includes a network slice database 306 that is configured to store any of the information utilized by the network slice engine 304 discussed below. The chassis 302 may also house a communication system 308 that is coupled to the network slice engine 304 and the application engine 305 (e.g., via a coupling between the communication system 308 and the processing system) and that may be provided by a Network Interface Controller (NIC), wireless communication systems (e.g., cellular wireless components (e.g., 5G cellular wireless components, BLUETOOTH® components, Near Field Communication (NFC) components, WiFi components, etc.), and/or any other communication components that would be apparent to one of skill in the art in possession of the present disclosure. However, while a specific endpoint computing device 300 has been illustrated, one of skill in the art in possession of the present disclosure will recognize that endpoint computing devices (or other devices operating according to the teachings of the present disclosure in a manner similar to that described below for the endpoint computing device 300) may include a variety of components and/or component configurations for providing conventional endpoint computing device functionality, as well as the functionality discussed below, while remaining within the scope of the present disclosure as well.

Referring now to FIG. 4, an embodiment of a method 400 for utilizing multiple network slices for an endpoint computing device is illustrated. As discussed below, the systems and methods of the present disclosure provide for the utilization of respective network slices for different functionality (e.g., different applications, different workloads, etc.) provided on any particular endpoint computing device. For example, a core network system that is coupled to a RAN system may allocate a plurality of a network slices and make each of the plurality of network slices available for use in wireless communications via the RAN system. An endpoint computing device may include first and second applications that are configured to operate on the endpoint computing device, and the endpoint computing device may detect each of the first application and the second application, determine a first networking connectivity requirement for the first application, and determine a second networking connectivity requirement for the second application. The endpoint computing device may then identify a first network slice that is allocated by the core network system, available via the RAN system, and that satisfies the first networking connectivity requirement for the first application. The endpoint computing device may also identify a second network slice that is allocated by the core network system, available via the RAN system, and that satisfies the second networking connectivity requirement for the second application. Then endpoint computing device then establishes a first connection for the first application with the first network slice, and establishes a second connection for the second application with the second network slice. Subsequently, the first application may exchange first communications via the RAN system and the core network system using the first network slice, and the second application may exchange second communications via the RAN system and the core network system using the second network slice. As such, network slicing is extended to general purpose endpoint computing devices running applications (or workloads) with different networking connectivity requirements by providing for the utilization of a respective network slice by each of those applications, thus optimizing the networking connectivity of the general purpose endpoint computing device on a per-application/per-workload/per functionality basis.

With reference to FIG. 5, an embodiment of conventional endpoint computing device network slicing functionality using the endpoint computing device multi-network slice utilization system 200 of FIG. 2 is illustrated for purposes of discussion and to contrast the endpoint computing device multi-network slice functionality of the present disclosure. As illustrated in FIG. 5, the core network system 202 (e.g., a 5G core network system) may operate to allocate network slices and make those network slices available to via the RAN system 204 (e.g., a 5G RAN system) for use in wireless communications. For example, arrows are provided within the core network system 202 in FIG. 5 to represent portions of spectrum that are available to the core network system 202, including a spectrum portion 500, a spectrum portion 502, and a spectrum portion 504 in the illustrated embodiment.

Furthermore, the allocation of network slices and the making of those network slices available via the RAN system 204 for use in wireless communications by the core network system 202 is illustrated in FIG. 5 by arrows provided in the RAN system 204, and may include the core network system 202 allocating a network slice 500 a from the spectrum portion 500 (as illustrated by the arrow between the spectrum portion 500 and the network slice 500 a), allocating a network slice 502 a from the spectrum portion 502 (as illustrated by the arrow between the spectrum portion 502 and the network slice 502 a), and allocating network slices 504 a and 504 b from the spectrum portion 504 (as illustrated by the respective arrow between the spectrum portion 504 and the network slices 504 a and 504 b). One of skill in the art in possession of the present disclosure would recognize that the allocation of network slices by a core network system, and the making of those network slices available by the core network system via a RAN system, may include a variety of conventional operations, and thus is not described herein in detail. Furthermore, one of skill in the art in possession of the present disclosure will appreciate that each network slice 500 a, 502 a, 504 a, and 504 b may provide particular networking characteristics including particular data transmission latency, particular data transmission throughput/bandwidth, particular data transmission reliability, other particular Quality of Service (QoS) characteristics, and/or other particular networking characteristics that would be apparent to one of skill in the art in possession of the present disclosure.

As also illustrated in FIG. 5, each of the endpoint computing devices 206 a-206 d may then operate to connect to a respective network slice in order to utilize that network slice for exchanging wireless communications via the RAN system 204 and the core network system 202 (i.e., wireless communications with other endpoint computing devices coupled to the RAN system 204, other endpoint devices coupled to a network that is coupled to the core network system 202, etc.) One of skill in the art in possession of the present disclosure would recognize that the connection to a network slice by an endpoint computing device, and the exchange of communications via a RAN system and core network system by that endpoint computing device using that network slice, may include a variety of conventional operations, and thus is not described herein in detail. As discussed above, the conventional endpoint computing device network slicing illustrated in FIG. 5 and described above tends to work well for “single-function” computing devices such as IoT computing devices (e.g., IoT power meter devices), autonomous driving computing device, factory automation computing devices, and/or other single-function endpoint computing devices known in the art that include particular networking connectivity requirements, as the networking characteristics of a single network slice to which an endpoint computing device conventionally connects do not substantially change during the networking session associated with that connection.

However, the conventional endpoint computing device network slicing illustrated in FIG. 5 and described above introduces inefficiencies when utilized with general purpose endpoint computing devices such as laptop/notebook computing devices, tablet computing devices, and mobile phones that provide multiple functions (e.g., via multiple applications operating on those general purpose endpoint computing devices), as the conventional provisioning of a conventional network slice with networking characteristics that satisfy a particular networking connectivity requirement to such general purpose endpoint computing devices will often result in a networking connection that is non-optimal for at least some of the functionality provided by the general purpose endpoint computing device (e.g., at least some of the applications or workloads operating on the general purpose endpoint computing device.) As described below, the endpoint computing device multi-network slice utilization systems and methods of the present disclosure remedy such inefficiencies by allowing multiple separate endpoint computing device functionalities provided by a single endpoint computing device (e.g., applications, workloads, etc.) to each connect to and utilize a respective network slice that includes networking characteristics that satisfy the networking connectivity requirements of that endpoint computing device functionality.

The method 400 begins at block 402 where an endpoint computing device detects applications. In the specific example provided below, the method 400 is described as being performed by the endpoint computing device 206 a. However, one of skill in the art in possession of the present disclosure will appreciate that the method 400 may be performed by any or all of the endpoint computing devices 206 a-206 d at the same (or different) times while remaining within the scope of the present disclosure as well. In an embodiment, at block 402, the application engine(s) 305 in the endpoint computing device 206 a/300 may operate to provide one or more applications for operation on the endpoint computing device 206 a/300. For example, at block 402, the application engine(s) 305 in the endpoint computing device 206 a/300 may operate to provide a video communication application, an audio communication application, a video streaming application, an office productivity application, a gaming application, and/or any other applications that would be apparent to one of skill in the art in possession of the present disclosure. As would be appreciated by one of skill in the art in possession of the present disclosure, the applications provided at block 402 may operate to provide (or be replaced by) workloads operating on the endpoint computing device(s), as well as any other endpoint computing device functionality that one of skill in the art in possession of the present disclosure would recognize that benefitting from the dedicated network slices functionality described below.

As such, in an embodiment of block 402, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to detect the applications provided by the application engine(s) 305. For example, at block 402, the network slice engine 304 in the endpoint computing device 206 a/300 may detect the applications provided by the application engine(s) 305 and operating on the endpoint computing device 206 a/300 in response to the launching of those applications, in response to respective network connection requests received from those applications, and/or in response to any other application detection event that would be apparent to one of skill in the art in possession of the present disclosure. As such, continuing with the specific example provided above, at block 402, the network slice engine 304 in the endpoint computing device 206 a/300 may detect a video communication application, an audio communication application, a video streaming application, an office productivity application, and/or a gaming application provided on the endpoint computing device 206 a/300. However, while the method 400 is described as detecting applications at block 402, one of skill in the art in possession of the present disclosure will appreciate how workloads and/or other functionality provided on the endpoint computing device 206 a/300 may be detected at block 402 while remaining within the scope of the present disclosure as well.

The method 400 then proceeds to block 404 where the endpoint computing device determines networking connectivity requirements for the detected applications. In an embodiment, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine a networking connectivity requirement for each of the applications detected at block 402. In an embodiment, the determination of the networking connectivity requirements for an application by the network slice engine 304 in the endpoint computing device 206 a/300 may include the application engine 305, which is providing an application, transmitting the networking connectivity requirements for that application to the network slice engine 304 (e.g., as IP header information in a data packet); the network slice engine 304 retrieving the networking connectivity requirements for an application (e.g., in response to the detection of that application) that may have been previously determined and stored in the network slice database 306 from the network slice database 306; and/or via any other networking connectivity requirement determination technique that would be apparent to one of skill in the art in possession of the present disclosure.

Continuing with the specific example provided above, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine networking connectivity requirements for a video communication application detected at block 402 that includes a relatively high bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively high reliability networking connectivity requirement. Similarly, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine networking connectivity requirements for an audio communication application detected at block 402 that includes a relatively low bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively high reliability networking connectivity requirements. Similarly, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine networking connectivity requirements for a video streaming application detected at block 402 that includes a relatively high bandwidth networking connectivity requirement, a relatively intermediate latency networking connectivity requirement, and a relatively intermediate reliability networking connectivity requirement.

Similarly, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine networking connectivity requirements for an office productivity application detected at block 402 that includes a relatively intermediate bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively low reliability networking connectivity requirements. Similarly, at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine networking connectivity requirements for a gaming application detected at block 402 that includes a relatively very high bandwidth networking connectivity requirement, a relatively very high latency networking connectivity requirement, and a relatively very high reliability networking connectivity requirement. However, while a few specific examples are provided, one of skill in the art in possession of the present disclosure will appreciate how different applications, workloads, and/or functionalities operating on and/or provided by an endpoint computing devices may include a variety of different networking connectivity requirements, and that any of those networking connectivity requirements may be determined at block 404 while remaining within the scope of the present disclosure as well.

Furthermore, in different embodiments, any particular application, workload, and/or functionality operating on the endpoint computing device 206 a/300 may include multiple application subsystems, workload subsystems, and/or functionality subsystems that have different networking connectivity requirements (e.g., an application operating on the endpoint computing device 206 a/300 may include a first application subsystem having a first networking connectivity requirement, a second application subsystem having a second networking connectivity requirement, and so on), and those applications subsystems, workload subsystems, and/or functionality subsystems may be detected at block 402 and their different networking connectivity requirements determined at block 404. Further still, in some embodiments, multiple applications operating on the endpoint computing device 206 a/300 may include the same networking connectivity requirement (or respective networking connectivity requirements that fall within a particular networking connectivity requirement range) and, as such, those applications may be detected, the networking connectivity requirements of those applications may be determined, and those applications may be grouped in an application container that is associated with networking connectivity requirement (or networking connectivity requirement range) of those applications. Yet, further still, while the grouping of applications with the same or similar networking connectivity requirements into an application container is described as being performed during the method 400, the application containers discussed above as being associated with an networking connectivity requirement or networking connectivity requirement range may be determined prior to the method 400, stored in the network slice database 306, and identified at block 404 from that network slice database 306 while remaining within the scope of the present disclosure as well.

The method 400 then proceeds to block 406 where the endpoint computing device identifies network slices that satisfy the networking connectivity requirements for the detected applications. In an embodiment, at block 406, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to identify a respective network slice that satisfies each networking connectivity requirement determined for each of the applications at block 404. With reference to FIG. 6A, the core network system 202 (e.g., a 5G core network system) may operate to allocate network slices and make those network slices available to via the RAN system 204 (e.g., a 5G RAN system) for use in wireless communications. For example, arrows are provided in the core network system 202 in FIG. 6A to represent portions of spectrum that is available to the core network system 202, including a spectrum portion 600, a spectrum portion 602, and a spectrum portion 604 in the illustrated embodiment.

Furthermore, the allocation of network slices and the making of those network slices available via the RAN system 204 for use in wireless communications by the core network system 202 is illustrated in FIG. 6A by arrows provided in the RAN system 204, and may include the core network system 202 allocating a network slice 600 a from the spectrum portion 600 (as illustrated by the arrow between the spectrum portion 600 and the network slice 600 a), allocating a network slice 602 a from the spectrum portion 602 (as illustrated by the arrow between the spectrum portion 602 and the network slice 602 a), and allocating network slices 604 a and 604 b from the spectrum portion 604 (as illustrated by the respective arrow between the spectrum portion 604 and the network slices 604 a and 604 b). One of skill in the art in possession of the present disclosure would recognize that the allocation of network slices by a core network system, and the making of those network slices available by the core network system via a RAN system, may include a variety of conventional operations, and thus is not described herein in detail. Furthermore, one of skill in the art in possession of the present disclosure will appreciate that each network slice 600 a, 602 a, 604 a, and 604 b may provide particular networking characteristics including particular data transmission latency, particular data transmission throughput/bandwidth, particular data transmission reliability, other particular QoS networking characteristics, and/or other particular networking characteristics that would be apparent to one of skill in the art in possession of the present disclosure.

In some embodiments, each network slice allocated by the core system network system 202 and made available via the RAN system 204 by the core network system 202 may be configured to identify the particular networking characteristics provided by that network slice. For example, each of the network slices 500 a, 502 a, 504 a, and 504 b may be configured to advertise its networking characteristics such that the network slice engine 304 in the endpoint computing device 206 a/300 may identify the networking characteristics of each network slice that is available for connection to the endpoint computing device 206 a/300. FIG. 6B illustrates how the network slice 600 a may advertise its networking characteristics 606 to the endpoint computing device 206 a (illustrated via a dashed arrow in FIG. 6B), the network slice 602 a may advertise its networking characteristics 608 to the endpoint computing device 206 a (illustrated via a dashed arrow in FIG. 6B), the network slice 604 a may advertise its networking characteristics 610 to the endpoint computing device 206 a (illustrated via a dashed arrow in FIG. 6B), and the network slice 604 b may advertise its networking characteristics 610 to the endpoint computing device 206 a (illustrated via a dashed arrow in FIG. 6B). One of skill in the art in possession of the present disclosure will appreciate that the dashed arrows in FIG. 6B may indicate the retrieval of the networking characteristics 606, 608, 610, and 612 by the network slice engine 304 in the endpoint computing device 206 a/300 via the network slice advertisements discussed above. In a specific example, any particular network slice may identify its networking characteristics via a network slice identifier, a network slice name, a network slice data traffic QoS (e.g., default/best effort, video streaming best effort, enterprise high priority, etc.), and/or a code (e.g., 0x00, 0x1A, 0X12, etc.).

As such, at block 406, the network slice engine 304 in the endpoint computing device 206 a/300 may identify the latency networking characteristics, the throughput/bandwidth networking characteristics, the reliability networking characteristics, other QoS networking characteristics, and/or any other networking characteristics provided by each of the network slices 600 a, 602 a, 604 a, and 604 b. Furthermore, while a particular technique for identifying networking characteristics of a network slice have been described, one of skill in the art in possession of the present disclosure will appreciate that other techniques for identifying networking characteristics of a network slice may fall within the scope of the present disclosure as well. In a specific example, a RAN controller in the RAN system 204 may inform the endpoint computing device about the number of network slices available to that endpoint computing device from the RAN system, and the QoS networking characteristics associated with each network slice, which allows the endpoint computing device to associate the data traffic provided by each application or workload operating on that endpoint computing device with a network slice that satisfies its network connectivity requirements, as discussed below.

Thus, at block 406, the network slice engine 304 in the endpoint computing device 206 a/300 may identify a respective one of the network slices 206 a-206 d that includes networking characteristics that satisfy the networking connectivity requirements of each of the applications detected at block 402. Continuing with the example provided above, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy the networking connectivity requirements for a video communication application detected at block 402 that includes a relatively high bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively high reliability networking connectivity requirement. Similarly, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy networking connectivity requirements for an audio communication application detected at block 402 that includes a relatively low bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively high reliability networking connectivity requirements. Similarly, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy determine networking connectivity requirements for a video streaming application detected at block 402 that includes a relatively high bandwidth networking connectivity requirement, a relatively intermediate latency networking connectivity requirement, and a relatively intermediate reliability networking connectivity requirement.

Similarly, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy networking connectivity requirements for an office productivity application detected at block 402 that includes a relatively intermediate bandwidth networking connectivity requirement, a relatively low latency networking connectivity requirement, and a relatively low reliability networking connectivity requirements. Similarly, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy networking connectivity requirements for a gaming application detected at block 402 that includes a relatively very high bandwidth networking connectivity requirement, a relatively very high latency networking connectivity requirement, and a relatively very high reliability networking connectivity requirement.

Furthermore, in some embodiments, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify respective network slices that include respective networking characteristics that satisfy different networking connectivity requirements for respective multiple application subsystems, workload subsystems, and/or functionality subsystems included in an application, workload, or functionality (e.g., a first network slice including first networking characteristics that satisfy a first networking connectivity requirement for a first application subsystem included in an application operating on the endpoint computing device 206 a/300, a second network slice including second networking characteristics that satisfy a second networking connectivity requirement for a second application subsystem included in that application operating on the endpoint computing device 206 a/300, and so on). Further still, in some embodiments, at block 406 the network slice engine 304 in the endpoint computing device 206 a/300 may identify a network slice that includes networking characteristics that satisfy the same networking connectivity requirement (or a networking connectivity requirement range) for multiple applications that have been grouped in an application container as discussed above.

As will be appreciated by one of skill in the art in possession of the present disclosure, the identification of respective network slices that include networking characteristics that satisfy the networking connectivity requirements of each application operating on the endpoint computing device 206 a/300 may include, for each application with a particular networking connectivity requirement, the identification of a network slice that includes networking characteristics that are closest to those networking connectivity requirements, that fall within some range of those networking connectivity requirements, and/or that one of skill in the art in possession of the present disclosure would recognize make that network slice the most desirable of the network slices that are available to the endpoint computing device 206 a/300 for providing that connection for that application. Furthermore, one of skill in the art in possession of the present disclosure will appreciate that situations may arise in which no network slices are available that include networking characteristics that satisfy the network connectivity requirements of an application and, in such situations, the network slice that includes networking characteristics that most closely satisfy the network connectivity requirements of that application may be identified for providing the connection for that application.

In some embodiments, the network slice engine 304 in the endpoint computing device 206 a/300 may be configured to request network slices with particular networking characteristics that satisfy the networking connectivity requirements of applications detected to block 402. For example, after determining the networking connectivity requirements for an application at block 404, the network slice engine 304 in the endpoint computing device 206 a/300 may transmit a network slice request communication via the RAN system 204 to the core network system 202 (e.g., via an available connection to the core network system 202 that may have been previously established using conventional techniques and/or the techniques described herein), with that network slice request communication providing a request to allocate a network slice having networking characteristics that satisfy the network connectivity requirements of the application, and make that network slice available via the RAN system 204. As such, the core network system 202 may receive that network slice request and, in response, may allocate a network slice having the requested network connectivity requirements, and make that network slice available via the RAN system 204 so that the network slice engine 304 in the endpoint computing device 206 a/300 may identify that network slice at block 406.

The method 400 then proceeds to block 408 where the endpoint computing device establishes connections for the detected applications with the respective network slices identified for those applications. In an embodiment, at block 408, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to establish a respective connection for each application operating on the endpoint computing device 206 a/300 with the network slice that was identified at block 406 as including networking characteristics that satisfy the networking connectivity requirements of that application. For example, at block 408, the network slice engine 304 in the endpoint computing device 206 a/300 may, for each application for which it identified a network slice at block 406, present that application as a virtual endpoint computing device in network slice connection communications exchanged with the RAN system 204, with the network slice communications operating to establish a connection between that application and the network slice that was identified for that application at block 406. As will be appreciated by one of skill in the art in possession of the present disclosure, the network slice communications and/or establishment of the connection between the network slice and the application that is presented as a virtual endpoint computing device may be similar to conventional network slice/physical endpoint device communications and/or connection establishment, with the exception of the application being presented as a virtual endpoint computing device in the network slice connection communications and/or connection establishment, and thus are not described herein in detail.

As such, with reference to FIG. 6C, at block 408, the network slice engine 304 in the endpoint computing device 206 a/300 may establish a connection 614 for a first application operating on the endpoint computing device 206 a with the network slice 600 a that was identified as having networking characteristics that satisfy the networking connectivity requirements determined for the first application, establish a connection 616 for a second application operating on the endpoint computing device 206 a with the network slice 602 a that was identified as having networking characteristics that satisfy the networking connectivity requirements determined for the second application, and establish a connection 618 for a third application operating on the endpoint computing device 206 a with the network slice 604 a that was identified as having networking characteristics that satisfy the networking connectivity requirements determined for the third application. While not illustrated, as discussed above one of skill in the art in possession of the present disclosure will appreciate that connections with multiple network slices for each application operating on any or all of the endpoint computing devices 206 b-206 c may be established in a similar manner while remaining within the scope of the present disclosure as well.

Furthermore, in some embodiments, at block 408 the network slice engine 304 in the endpoint computing device 206 a/300 may establish connections for respective multiple application subsystems, workload subsystems, and/or functionality subsystems included in an application, workload, or functionality with respective network slices that include respective networking characteristics that satisfy their different networking connectivity requirements (e.g., establishing a first connection with a first network slice including first networking characteristics that satisfy a first networking connectivity requirement for a first application subsystem included in an application operating on the endpoint computing device 206 a/300, establishing a second connection with a second network slice including second networking characteristics that satisfy a second networking connectivity requirement for a second application subsystem included in that application operating on the endpoint computing device 206 a/300, and so on). Further still, in some embodiments, at block 408 the network slice engine 304 in the endpoint computing device 206 a/300 may establish a connection with a network slice that includes networking characteristics that satisfy the same networking connectivity requirement (or a networking connectivity requirement range) for multiple applications that have been grouped in an application container. As such, one of skill in the art in possession of the present disclosure will appreciate that any single endpoint computing device may appear to the RAN system 204 and/or the core network system 202 as many (e.g., tens, hundreds, or more) endpoint computing devices due to the many applications operating on that single endpoint computing device being presented as respective virtual endpoint computing devices.

The method 400 then proceeds to block 410 where the endpoint computing device exchanges communications for the detected applications using the identified network slices. In an embodiment, at block 410, communications may be exchanged between for each application using the connection established with its respective network slice that satisfies its respective networking connectivity requirements. As such, with reference to FIG. 6C, at block 410, the network slice engine 304 in the endpoint computing device 206 a/300 may utilize its communication system 308 to exchange communications via the connection 614 with the network slice 600 a for the first application operating on the endpoint computing device 206 a (e.g., with a device coupled to the RAN system 204, a device coupled to the core network system 202 via a network, etc.), may utilize its communication system 308 to exchange communications via the connection 616 with the network slice 602 a for the second application operating on the endpoint computing device 206 a (e.g., with a device coupled to the RAN system 204, a device coupled to the core network system 202 via a network, etc.), and may utilize its communication system 308 to exchange communications via the connection 618 with the network slice 602 a for the third application operating on the endpoint computing device 206 a (e.g., with a device coupled to the RAN system 204, a device coupled to the core network system 202 via a network, etc.) As will be appreciated by one of skill in the art in possession of the present disclosure, the exchange of communications via a connection with a network slice at block 410 may be similar to conventional network slice communication exchanges, with the exception of that multiple applications operating on the endpoint computing device 206 a/300 may be exchanging communications via their respective connections with their respective network slices that each include respective networking characteristics that satisfy the networking connectivity requirements of those applications. As discussed below, each of the network slices provided by the core network system 202 are isolated from each other and, as such, any application or workload that is operating on an endpoint computing device and that is utilizing a particular network slice will be unaware of the other networks available via the other network slices being utilized by other applications or workloads operating on that same endpoint computing device.

Furthermore, in some embodiments, at block 408 the network slice engine 304 in the endpoint computing device 206 a/300 may operate to exchange communications for respective multiple application subsystems, workload subsystems, and/or functionality subsystems included in an application, workload, or functionality via connections provided with respective network slices (e.g., exchanging communications via a first connection with a first network slice for a first application subsystem included in an application operating on the endpoint computing device 206 a/300, exchanging communications via a second connection with a second network slice for a second application subsystem included in that application operating on the endpoint computing device 206 a/300, and so on). Further still, in some embodiments, at block 408 the network slice engine 304 in the endpoint computing device 206 a/300 may exchange communications via a connection with a network slice for multiple applications that have been grouped in an application container as discussed above.

The method 400 then proceeds to decision block 412 where it is determined whether a detected application is unavailable. In an embodiment, at decision block 412, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to determine whether an application for which a respective connection was established with a respective network slice has become unavailable. For example, an application, workload, or other functionality operating on the endpoint computing device may complete, be shut down, and/or may otherwise become unavailable in a manner that does not utilize the network slice with which that application, workload, or other functionality was connected at block 410. As such, the network slice engine 304 in the endpoint computing device 206 a/300 may operate to continuously or periodically to monitor applications (or application subsystems in an application, or applications grouped in an application container) for which a connection with a network slice was provided at block 408 to determine whether that application (or application subsystem) has become unavailable or is otherwise not utilizing the network slice to which it was connected. However, while a specific technique for monitoring for the use of a network slice has been described, one of skill in the art in possession of the present disclosure will appreciate that network slice utilization may be determined in a variety of other manners that will fall within the scope of the present disclosure as well.

If, at decision block 412, it is determined that no detected applications are unavailable, the method 400 returns to block 410. As such, in response to determining that each application (or application subsystem in an application, or application grouped in an application container) for which a connection with a network slice was established at block 408 is still utilizing that network slice, the method 400 may loop to continue to exchange communications for applications using the connections to their network slices at block 410, and monitor whether any of those applications have become unavailable at decision block 412. If at decision block 406, it is determined that a detected application is not available, the method 400 proceeds to block 414 where the endpoint computing device ends the connection with the identified network slice for the unavailable detected application. In an embodiment, at block 414 and in response to determining that an application (or application subsystem in an application, or all applications grouped in an application container) is no longer utilizing a connection to a network slice that was provided at block 408, the network slice engine 304 in the endpoint computing device 206 a/300 may end that connection with the network slice for that application (or application subsystem in an application, or application container), and release that network slice for use by other applications and/or endpoint computing devices. As will be appreciated by one of skill in the art in possession of the present disclosure, the ending of a connection with a network slice at block 414 may be similar to conventional connection ending operations, and thus is not described herein in detail. The method 400 may then loop to continue to exchange communications for available applications using the connections to their network slices at block 410, monitor whether any of those applications have become unavailable at decision block 412, and end connections to network slices that are no longer being utilized.

In some embodiments, repeated performance of the method 400 may allow the network slice engine 304 in the endpoint computing devices 300 to perform intelligent network slice operations based on learned behavior of the endpoint computing device 300 and/or the applications provided thereon. For example, the network slice engine 304 in the endpoint computing device 300 may monitor the use of applications on the endpoint computing device 300, the time of such application use on the endpoint computing device 300, locations of the endpoint computing device 300, and/or any other information that would be apparent to one of skill in the art in possession of the present disclosure, and may subsequently utilize that information to reserve network slices that include networking characteristics that satisfy the networking connectivity requirements of particular applications. As such, when an endpoint computing device repeatedly operates a particular application at a particular time and in a particular location that utilizes a particular network slice that includes networking characteristics that satisfy its networking connectivity requirements, the network slice engine 304 in the endpoint computing device 300 may learn that behavior and subsequently operate to reserve that network slice at the learned reoccurring application use time for use by the learned application in the learned location. However, while a specific intelligent network slice operation is described, one of skill in the art in possession of the present disclosure will recognize that other intelligent network slice operations may be performed that will fall within the scope of the present disclosure as well.

Thus, systems and methods have been described that provide for the utilization of respective network slices for different functionality (e.g., different applications, different workloads, etc.) provided on any particular endpoint computing device. For example, a 5G core network system that is coupled to a 5G RAN system may allocate a plurality of a network slices and make each of the plurality of network slices available for use in wireless communications via the 5G RAN system. An endpoint computing device may include first and second applications that are configured to operate on the endpoint computing device, and the endpoint computing device may detect each of the first application and the second application, determine a first networking connectivity requirement for the first application, and determine a second networking connectivity requirement for the second application. The endpoint computing device may then identify a first network slice that is allocated by the 5G core network system, available via the 5G RAN system, and that includes networking characteristics that satisfy the first networking connectivity requirements for the first application. The endpoint computing device may also identify a second network slice that is allocated by the 5G core network system, available via the 5G RAN system, and that includes networking characteristics that satisfy the second networking connectivity requirements for the second application. The endpoint computing device then establishes a first connection for the first application with the first network slice, and establishes a second connection for the second application with the second network slice. Subsequently, the first application may exchange first communications via the 5G RAN system and the 5G core network system using the first network slice, and the second application may exchange second communications via the 5G RAN system and the 5G core network system using the second network slice. As such, network slicing is extended to general purpose endpoint computing devices running applications (or workloads) with different networking connectivity requirements by connecting each of those applications (or workloads) to a respective network slice with networking characteristics that satisfy its networking connectivity requirements, thus optimizing the networking connectivity of the general purpose endpoint computing device on a per-application/per-workload/per functionality basis.

Referring now to FIGS. 7A and 7B, an embodiment of an endpoint computing device 700 is illustrated that may provide the endpoint computing device network slice certificate provisioning and management system of the present disclosure, and in some embodiments may provide any or all of the endpoint computing devices 206 a-206 d discussed above with reference to FIG. 2. As such, the endpoint computing device 700 may be provided by the IHS 100 discussed above with reference to FIG. 1 and/or may include some or all of the components of the IHS 100, and in specific examples may be provided by server computing devices, networking computing devices, storage systems, desktop computing devices, laptop/notebook computing devices, tablet computing devices, mobile phones, and/or other computing devices known in the art. Furthermore, while illustrated and discussed as an endpoint computing device, one of skill in the art in possession of the present disclosure will recognize that the functionality of the endpoint computing device 700 discussed below may be provided by other devices that are configured to operate similarly as discussed below.

In the illustrated embodiment, the endpoint computing device 700 includes a chassis 702 that houses the components of the endpoint computing device 700, only some of which are illustrated below. For example, the chassis 702 may house a processing system (not illustrated, but which may include the processor 102 discussed above with reference to FIG. 1) and a memory system (not illustrated, but which may include the memory 114 discussed above with reference to FIG. 1) that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a network slice certificate provisioning and management engine 704 that is configured to perform the functionality of the network slice certificate provisioning and management engines and/or endpoint computing devices discussed below. Furthermore, in some embodiments, some or all of the functionality of the endpoint computing device 300 of FIG. 3 and the endpoint computing device 700 may be combined or otherwise provided in the same endpoint computing device such that a single endpoint computing device is configured to perform any of the functionality described herein for the network slice certificate provisioning and management engine 704 and the network slice engine 304.

As illustrated in FIG. 7B, in some embodiments, the network slice certificate provisioning and management engine 704 may be provided by hardware 704 a, firmware 704 b, and/or in many examples, a Basic Input/Output System (BIOS) 704 c that may be included as part of, or provided by, the firmware 704 b. One of skill in the art in possession of the present disclosure will appreciate that the BIOS 704 c may be utilized to perform initialization of the hardware 704 a when the endpoint computing device 700 is operating in a pre-boot environment (as well as provide runtime services for operating systems and/or other programs when the endpoint computing device 700 is operating in a runtime environment), and in a specific example, the BIOS 704 c may include a BIOS processing system and a BIOS memory system (e.g., as part of the hardware 704 a and/or firmware 704 b that provide the BIOS 704 c) that includes instructions that, when executed by the BIOS processing system, cause the BIOS processing system to provide at least some of the functionality of the network slice certificate provisioning and management engine 704.

Furthermore, in some of the examples provided below, the hardware 704 a and firmware 704 b may provide an Embedded Controller that may be configured to operate while a processing system in the endpoint computing device 700 (e.g., a CPU) is not operating. In a specific example, the Embedded Controller may include an Embedded Controller processing system and an Embedded Controller memory system (e.g., as part of the hardware 704 a and/or firmware 704 b that provide the Embedded Controller) that includes instructions that, when executed by the Embedded Controller processing system, cause the Embedded Controller processing system to provide at least some of the functionality of the network slice certificate provisioning and management engine 704. However, while the functionality of the network slice certificate provisioning and management engine 704 is described below as being provided by the BIOS 704 c and Embedded Controller, that functionality may also be provided by other firmware subsystems or modules while remaining within the scope of the present disclosure as well. Furthermore, while described as a “BIOS”, one of skill in the art in possession of the present disclosure will appreciate that the BIOS 704 c may be replaced and/or otherwise provided by a Universally Extensible Firmware Interface (UEFI) system, and/or other initialization systems while remaining within the scope of the present disclosure as well.

Returning to FIG. 7A, the chassis 702 may also house a storage system (not illustrated, but which may include the storage 108 discussed above with reference to FIG. 1) that is coupled to the network slice certificate provisioning and management engine 704 (e.g., via a coupling between the storage system and the processing system) and that includes a network slice certificate provisioning and management database 706 that is configured to store any of the information utilized by the network slice certificate provisioning and management engine 704 discussed below. The chassis 702 may also house a communication system 708 that is coupled to the network slice certificate provisioning and management engine 704 (e.g., via a coupling between the communication system 708 and the processing system) and that may be provided by a Network Interface Controller (NIC), wireless communication systems (e.g., 5G cellular wireless components, BLUETOOTH®, Near Field Communication (NFC) components, WiFi components, etc.), and/or any other communication components that would be apparent to one of skill in the art in possession of the present disclosure. While a specific endpoint computing device 700 has been illustrated, one of skill in the art in possession of the present disclosure will recognize that endpoint computing devices (or other devices operating according to the teachings of the present disclosure in a manner similar to that described below for the endpoint computing device 700) may include a variety of components and/or component configurations for providing conventional endpoint computing device functionality, as well as the functionality discussed below, while remaining within the scope of the present disclosure as well.

Referring now to FIG. 8, an embodiment of a method 800 for provisioning a certificate on and managing an endpoint computing device is illustrated. As described below, the systems and methods of the present disclosure may provide for the provisioning of a certificate on an endpoint computing device using a connection to a network slice, and the subsequent use of that certificate to perform secure out-of-band management operations. For example, a core network system that is coupled to the RAN system may allocate a plurality of a network slices and make each of the plurality of network slices available for use in wireless communications via the RAN system, and an endpoint computing device may establish a first network connection with a first network slice included in the plurality of network slices, and perform certificate provisioning operations via certificate provisioning wireless communications over the first network connection with the first network slice in order to provision a certificate for the endpoint computing device. The endpoint computing device may then use the certificate provisioned on the endpoint computing device to verify at least one server device to provide at least one verified server device, and perform secure network communications with the at least one verified server device that may include out-of-band management operations. As discussed below, the systems and methods of the present disclosure may utilize some of the techniques described above as being performed by the endpoint computing device multi-network slice utilization system 200 in order to perform certificate provisioning operations and out-of-band management operations on the same endpoint computing device via separate network slices. As such, the cost and complexity associated with conventional certificate provisioning operations may be reduced via the use of network slice(s) available via a 5G core network system in order to provision certificates on endpoint computing devices and, in some cases, provide out-of-band management of those endpoint computing devices.

The method 800 begins at block 802 where an endpoint computing device performs initialization operations while operating in a pre-boot environment. In an embodiment, at or prior to block 802, the endpoint computing device 206 a/700 may be powered on, reset, booted, and/or otherwise initialized such that the endpoint computing device 206 a/700 enters a pre-boot environment. As will be understood by one of skill in the art in possession of the present disclosure, computing devices such as server computing devices, networking computing devices, storage systems, desktop computing devices, laptop/notebook computing devices, tablet computing devices, and mobile phones discussed above, may perform a variety of initialization operations (e.g., boot operations) in order to initialize that computing device so that it may enter a runtime environment by, for example, providing an operating system for use on the computing device by a user. Furthermore, as discussed above, the BIOS 704 c may be provided by one or more firmware modules that perform hardware initialization during the initialization process (e.g., a boot process, a power-on startup process, etc.), and thus may operate to perform a variety of conventional initialization operations in some examples of block 802 (e.g., by providing the first software module that is run on the endpoint computing device 206 a/700 following power-on, reset, or boot, initializing and testing the hardware 704 a in the endpoint computing device 206 a/700, and/or performing any of a variety of BIOS initialization operations that would be apparent to one of skill in the art in possession of the present disclosure.) However, while a few examples have been provided, one of skill in the art in possession of the present disclosure will appreciate that endpoint computing devices may perform initialization operations while operating in a pre-boot environment in a variety of manners that will fall within the scope of the present disclosure as well.

The method 800 then proceeds to block 804 where the endpoint computing device establishes first network connection(s) with respective network slice(s). In an embodiment, the method 400 may be performed by the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 anytime it is determined that the endpoint computing device 206 a/700 is initializing for the first time and/or otherwise initializing in a manner that requires a certificate to be provisioned on the endpoint computing device 700 For example, one of skill in the art in possession of the present disclosure will recognize that conventional endpoint computing devices may be provisioned with certificates the very first time that endpoint computing device for use in a corporate environment, when an endpoint computing device becomes non-compliant with network requirements, when an endpoint computing device is re-imaged, and/or in a variety of other scenarios known in the art. However, endpoint computing devices are typically provisioned a certificate once due to the difficulties associated with conventional certificate provisioning, discussed above, and the teachings of the present disclosure intend to provide certificate provisioning systems and methods that reduce the difficulties associated with conventional certificate provisioning and make it relatively quick and simple to provisioning certificates on endpoint computing devices whenever needed. As such, certificate provisioning according to the method 800 may be performed whenever an endpoint computing device changes ownership, is lost/stolen, is decommissioned, and/or any other situation that would be apparent to one of skill in the art in possession of the present disclosure. Furthermore, as will be appreciated by one of skill in the art in possession of the present disclosure, the revocation and expiration of certificates as part of the certificate lifecycle may be managed over the same interface(s) described herein.

Thus, in response to determining that the endpoint computing device 206 a/700 is initializing for the first time and/or otherwise initializing in a manner that requires a certificate to be provisioned on the endpoint computing device 700, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may operate to establish one or more first network connections with respective network slice(s). For example, the BIOS 704 c may perform some network connection establishment operations that are similar to those described above as being performed by the network slice engine 304 to establish a connection with a first network slice that was allocated by the core network system 202 and made available via the RAN system 204.

Similarly as described above, the core network system 202 (e.g., a 5G core network system) discussed above may operate to allocate network slices and make those network slices available to via the RAN system 204 (e.g., a 5G RAN system) for use in wireless communications. For example, similarly as discussed above with reference to the core network system 202 in FIG. 5, the core network system 202 may allocate portions of spectrum (e.g., a first spectrum portion in the examples below) that are available to the core network system 202. With reference to FIG. 9A, the allocation of a network slice and the making of that network slice available by the core network system 202 via the RAN system 204 for use in wireless communications is illustrated by arrows provided in the RAN system 204, and may include the core network system 202 allocating a first network slice 900 from the first spectrum portion. As discussed above, one of skill in the art in possession of the present disclosure would recognize that the allocation of network slices by a core network system, and the making of those network slices available by the core network system via a RAN system, may include a variety of conventional operations, and thus is not described herein in detail.

As such, in an embodiment of block 804, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may perform some network connection establishment operations (e.g., which are similar to those described above as being performed by the network slice engine 304) to establish a network connection 902 with the first network slice 900. As will be appreciated by one of skill in the art in possession of the present disclosure, in some embodiments, the identification of the first network slice 900 based on networking connectivity requirements for the certificate provisioning operations discussed below and networking characteristics of the first network slice 900 (i.e., similarly as discussed above for the identification of networking connectivity requirement for an application and networking characteristics for a network slice) need not necessarily be performed during the method 800, and thus at block 804 the first network slice 900 may simply be identified as an available network slice for the network connection 902 prior to establishing the network connection 902 with the first network slice 900. However, the performance of network slice identification based on networking connectivity requirements for the certificate provisioning operations discussed below and networking characteristics of the first network slice 900 will fall within the scope of the present disclosure as well.

Thus, at block 804, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may identify itself, a BIOS subsystem (e.g., a networking module in the BIOS 704 c), and/or some other functionality in the network slice certificate provisioning and management engine 704 as a virtual endpoint computing device in network slice connection communications exchanged with the RAN system 204, with the network slice communications operating to establish the network connection 902 with the first network slice 900. As will be appreciated by one of skill in the art in possession of the present disclosure, the network slice communications and/or establishment of the network connection 902 between the first network slice 900 and the BIOS 704 c, BIOS subsystem, or other BIOS functionality that is presented as a virtual endpoint computing device may be similar to conventional network slice/physical endpoint device communications and/or connection establishment, with the exception of the BIOS 704 c, BIOS subsystem, or other BIOS functionality being presented as a virtual endpoint computing device in the network slice connection communications and/or connection establishment, and thus are not described herein in detail.

In some embodiments of block 804, the BIOS 704 c may also establish a network connection with a second network slice that was allocated by the core network system 202 and made available via the RAN system 204. For example, similarly as discussed above with reference to the core network system 202 in FIG. 5, the core network system 202 may allocate other portions of spectrum (e.g., a second spectrum portion in addition to the first spectrum portion in the examples below) that are available to the core network system 202. With reference to FIG. 9B, the allocation of a second network slice and the making of that second network slice available by the core network system 202 via the RAN system 204 for use in wireless communications is illustrated by arrows provided in the RAN system 204, and may include the core network system 202 also allocating a second network slice 904 from the second spectrum portion in addition to the first network slice 900. As discussed above, one of skill in the art in possession of the present disclosure would recognize that the allocation of network slices by a core network system, and the making of those network slices available by the core network system via a RAN system, may include a variety of conventional operations, and thus is not described herein in detail.

As such, in an embodiment of block 804, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may perform some network connection establishment operations to also establish a network connection 906 with the second network slice 904 in addition to the network connection 902 with the first network slice 902. As will be appreciated by one of skill in the art in possession of the present disclosure, in some embodiments, the identification of the second network slice 904 based on networking connectivity requirements for the out-of-band management operations discussed below and networking characteristics of the second network slice 904 (i.e., similarly as discussed above for the identification of networking connectivity requirement for an application and networking characteristics for a network slice) need not necessarily be performed during the method 800, and thus at block 804 the second network slice 904 may simply be identified as an available network slice for the network connection 906 prior to establishing the network connection 906 with the second network slice 904. However, the performance of network slice identification based on networking connectivity requirements for the out-of-band management operations discussed below and networking characteristics of the network slice 904 will fall within the scope of the present disclosure as well.

As discussed above and as will be appreciated by one of skill in the art in possession of the present disclosure, the network connection 902 to the first network slice 900 and the network connection 906 to the second network slice 904 may be provided as isolated connections via, for example, the isolation of the first network slice 900 and the second network slice 904, and thus information transmitted over either of the network connection 902 and the network connection 906 may not be accessible via the other connection. However, as discussed below, in some embodiments the network connection 902 to the first network slice 900 may be utilized for the out-of-band management operations following its use for certificate provisioning operations, and thus multiple network connections to respective network slices (e.g., the network connection 906 to the second network slice 904 in the example above) need not be established in those embodiments.

Thus, at block 804, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may identify itself, a BIOS subsystem (e.g., a networking module in the BIOS 704 c), and/or some other functionality in the network slice certificate provisioning and management engine 704 as a virtual endpoint computing device in network slice connection communications exchanged with the RAN system 204, with the network slice communications operating to establish the network connection 906 with the second network slice 904. As will be appreciated by one of skill in the art in possession of the present disclosure, the network slice communications and/or establishment of the network connection 906 between the second network slice 904 and the BIOS 704 c, BIOS subsystem, or other BIOS functionality that is presented as a virtual endpoint computing device may be similar to conventional network slice/physical endpoint device communications and/or connection establishment, with the exception of the BIOS 704 c, BIOS subsystem, or other BIOS functionality being presented as a virtual endpoint computing device in the network slice connection communications and/or connection establishment, and thus are not described herein in detail.

The method 800 then proceeds to block 808 where the endpoint computing device performs certificate provisioning operations via certificate provisioning wireless communications over one of the first network connection(s) with the network slice(s) to provision a certificate on the endpoint computing device. In an embodiment, at block 806 and following the establishment of the network connection 902 to the first network slice 900, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may utilize the network connection 902 to the first network slice 900 to connect to a certificate provisioning server system that is coupled to the core network system 202 via a network, and exchange certificate provisioning wireless communications to perform certificate provisioning operations via that network connection 902 to the first network slice 900. As will be appreciated by one of skill in the art in possession of the present disclosure, the certificate provisioning operation performed by the endpoint computing device 700 and the certificate provisioning server system may include any of a variety of conventional certificate provision operations that operate to allow the endpoint computing device 700 to retrieve a certificate from the certificate provisioning server system and provision that certificate on the endpoint computing device 700. As such, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may provision a certificate received via the network connection 904 from the certificate provisioning server system on the endpoint computing device 700, which may include the storing of that certificate in the network slice certificate provisioning and management database 306.

The method 800 then proceeds to block 810 where the endpoint computing device performs verification operations with one or more server devices using the certificate provisioned on the endpoint computing device in order to provide one or more verified server devices. In an embodiment, at block 810, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may utilize the certificate provided on the endpoint computing device 700 at block 808 in order to verify the endpoint computing device 206 a/700 with one or more out-of-band management server devices in an out-of-band management server system that may be coupled to the core network system 202 via a network. However, while verification with out-of-band server devices is described herein, verification with any other server devices to provide for secure communications utilized for the performance of any other types of operations (e.g., other than out-of-band management operations described herein) will fall within the scope of the present disclosure as well. As will be appreciated by one of skill in the art in possession of the present disclosure, verification with server devices using a certificate provisioned on an endpoint computing device may include a variety of conventional operations, and thus is not described herein in detail. As such, following block 810, any server devices (e.g., the out-of-band management server device(s) discussed above) may be considered verified server devices with which the endpoint computing device 700 may perform secure communications (e.g., to conductive the out-of-band management operations discussed herein.)

The method 800 then proceeds to block 812 where the endpoint computing device enters a runtime environment and establishes a second network connection. In an embodiment, at block 812 and following the verification operations performed using the certificate at block 810, the endpoint computing device 206 a/700 may enter a runtime state in which an operating system 908 is provided, as illustrated in FIGS. 9C and 9D, and the operating system 908 may take control of the runtime operations for the endpoint computing device 700. In response to entering the runtime environment, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may provide access to the certificate to the operating system 908, and one or more subsystems in the endpoint computing device 700 may operate to establish a second network connection for use by the operating system 908 (e.g., with the certificate) for performing secure network communications (e.g., in response to performing verification operations similar to those described above).

As will be appreciated by one of skill in the art in possession of the present disclosure, the second network connection provided for the operating system 908 may be considered an in-band connection (i.e., relatively to the out-of-band connection discussed above), and may be provided by a network slice allocated by the core network system 202 via the RAN system 204, by other wireless network connections (e.g., a Wifi network connection), by a wired network connection (e.g., an Ethernet connection), and/or by a variety of other network connection technologies that would be apparent to one of skill in the art in possession of the present disclosure. Thus, at block 812, the in-band connection may be established for the operating system 908, and the operating system 908 may utilize the certificate in order to verify the endpoint computing device 206 a/700 with any server devices with which it communicates via that in-band connection in a manner similar to that described above.

The method 800 may then proceed to optional block 814 where the endpoint computing device may end the first network connection with the network slice that was used for the certificate provisioning operations. In an embodiment, when optional block 814 is performed, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may operate to end one of the multiple network connections established at block 804 to its respective network slice. For example, with reference to FIGS. 9B and 9C, at optional block 814 the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may end the network connection 902 to the first network slice 900 (illustrated in FIG. 9B) such that only the network connection 906 to the second network slice 904 remains (illustrated in FIG. 9C.) As such, in some embodiments, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may establish the network connection 902 to the first network 900 for the purposes of performing the certificate provisioning operations discussed above, while establishing the network connection 906 to the second network slice 904 for the purposes of performing the out-of-band management operations discussed below, and following the provisioning of the certificate on the endpoint computing device 206 a/700 (and using the certificate to establish secure out-of-band management communications via the network connection 906 to the second network slice 904), the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may end the network connection 902 to the first network slice 900.

However, in other embodiments when optional block 814 is not performed, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may operate to transition from using the network connection 902 to the first network slice 900 for certificate provision operations to using the network connection 902 to the first network slice 900 for out-of-band management operations. For example, with reference to FIGS. 9A and 9D, the network slice certificate provisioning and management engine 704 provided by the BIOS 704 c in the endpoint computing device 206 a/700 may pass control of the network connection 902 to the first network slice 900 (illustrated in FIG. 9A) to an Embedded Controller provided by the hardware 704 a and firmware 704 b (as illustrated in FIG. 9D) subsequent to the use of the network connection 902 to the first network slice 900 to provision the certificate on the endpoint computing device 206 a/700 and use of that certificate to perform verification operations as discussed above. As such, in some embodiments, the BIOS 704 c provided by the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 may establish the network connection 902 to the first network slice 900 for the purposes of performing the certificate provisioning operations discussed above, and once the certificate is provisioned on the endpoint computing device 206 a-700 and verification operations have been performed by BIOS 704 c, may pass control of the network connection 902 to the first network slice 900 to an Embedded Controller provided by the network slice certificate provisioning and management engine 704 for the purposes of performing the out-of-band management operations discussed below.

The method 800 then proceeds to block 816 where the endpoint computing device performs out-of-band management operations via out-of-band management wireless communications over one of the first network connections with the respective network slice(s). In the embodiment illustrated in FIG. 9C, at block 816, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 (e.g., an Embedded Controller provided by the hardware 704 a and firmware 704 b) may operate to perform out-of-band management wireless operations via out-of-band wireless communications transmitted over the network connection 906 with the second network slice 904. In the embodiment illustrated in FIG. 9D, at block 816, the network slice certificate provisioning and management engine 704 in the endpoint computing device 206 a/700 (e.g., an Embedded Controller provided by the hardware 704 a and firmware 704 b) may operate to perform out-of-band management wireless operations via out-of-band wireless communications transmitted over the network connection 902 with the first network slice 900. As will be appreciated by one of skill in the art in possession of the present disclosure, the out-of-band management communications performed at block 816 may include any of a variety of management communications that may be performed out-of-band and separate from the in-band communications being performed by the operating system 908, with the isolated network slices 900 or 902 providing for secure out-of-band management communications.

Thus, systems and methods have been described to provision a certificate on an endpoint computing device using a connection to a network slice in order to, for example, provide for the performance of secure out-of-band management operations. For example, a 5G core network system that is coupled to a 5G Radio Access Network (RAN) system may allocate a plurality of a network slices and make each of the plurality of network slices available for use in wireless communications via the 5G RAN system, and an endpoint computing device may establish a first network connection with a first network slice included in the plurality of network slices, and perform certificate provisioning operations via certificate provisioning wireless communications over the first network connection with the first network slice in order to provision a certificate for the endpoint computing device. The endpoint computing device may then use the certificate provisioned on the endpoint computing device to perform verification operations with at least one server device to provide at least one verified server device, and perform secure network communications with the at least one verified server device that may include the out-of-band management operations described above. As discussed below, the systems and methods of the present disclosure may utilize endpoint computing device multi-network slice utilization techniques in order to perform certificate provisioning operations and out-of-band management operations on the same endpoint computing device via separate network slices. As such, the cost and complexity associated with conventional certificate provisioning operations (e.g., associated with manual certificate provisioning and/or conventional automated certificate provisioning) may be reduced via the use of available network slice(s) to provision certificates on endpoint computing devices and provide out-of-band management of those endpoint computing devices.
